Can, convenient operation Based Intelligent Control；Novel appearance, simple in construction is convenient for carrying dismounting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is further described.
In Fig. 1, including motor housing 1, gear-box 2, keypad 3, motor 4, friction plate 5, plain thrust bearing 6, torsion spring
7, brake gear 8, drive shaft 9, screw mandrel 10, feed screw nut 11, outer tube 12, inner tube 13, latch 14, footing bearing 15, first watt
Lid the 16, second FE Tiler 17 etc..
As it is shown in figure 1, the present invention is a kind of motor-driven jack, including gear-box 2 and for the electricity driving gear-box 2 to operate
Machine 4, the outfan of gear-box 2 arranges drive shaft 9, drive shaft 9 lower end connection wire rod 10, threaded feed screw nut on screw mandrel 10
11, feed screw nut 11 external peripheral surface fixes inner tube 13, sheathed outer tube 12 outside inner tube 13, and described outer tube 12 upper end is fixed on
Bottom gear-box 2, inner tube 13 lower end connects footing bearing 15 by latch 14；In described drive shaft 9, brake gear 8 is set.
Brake gear 8 includes friction plate 5, single thrust bearing 6, torsion spring the 7, first FE Tiler the 16, second FE Tiler 17, wherein rubs
Pad 5 is arranged at drive shaft 9 upper position, sets gradually the second FE Tiler 17, single thrust bearing 6, first watt below friction plate 5
Lid 16, described first FE Tiler 16 is fixing with drive shaft 9 to be connected, and torsion spring 7 is arranged at first FE Tiler the 16, second FE Tiler 17 outer surface.
The tube surfaces of footing bearing 15 is the most uniform offers some through holes, and radial direction through hole is offered in inner tube 13 lower end,
Described radial direction through hole is connected by latch 14 with arbitrary through hole of seat tube surface.
Screw mandrel 10 is ball screw
Motor 4 top arranges motor housing 1, and motor housing 1 side is provided for controlling the keypad 3 of motor 4 operating mode.The present invention
The built-in PCB of keypad 3 in product, can be realized automatic lifting memory function by PCB.
The work process of the present invention is as follows: motor 4 is controlled by PCB circuit, is converted to by high-speed electric expreess locomotive 4 by gear-box 2
The high pulling torque slow-speed of revolution exports, and drives drive shaft 9 so that screw mandrel 10 rotates, and feed screw nut 11 fixes with inner tube 13, screw mandrel spiral shell
Mother 11 and screw mandrel 10 relative motion, thus realize axially-movable between inner tube 13, outer tube 12, it is finally reached the merit that elongation is shortened
Can, simultaneously by the position of regulating pin 14 with footing bearing 15, it is achieved height fine adjusting function.
Uphill process: plain thrust bearing 6 works, friction plate 5 is static, and brake gear 8 separates rotation thus screw mandrel 10 revolves
Turn the elongation of drive jack.
Decline process: torsion spring 7 wraps extremely, brake gear 8 becomes an integrated model, now friction plate 5 and brake gear 8 phase
Force of sliding friction is produced, it is achieved brake at any time to moving.
Product of the present invention is that one is driven by motor 4, and keypad 3 controls, and is extended by screw mandrel 10 or shortens, thus reaching
To supporting regulation effect.
